The consequence of risk selection is that the per capita claims cost and, consequently, premiums begin to rise for those insurers who are left with a higher proportion of less healthy individuals. This is a breach of the solidarity principle, which is fundamental to genuine community rating. Risk equalisation addresses this by limiting the extent to which certain healthier people, by benefiting from lower premiums, or their insurers, by taking a higher profit margin, can gain at the expense of other health insurance consumers. In short, risk equalisation aims to equitably adjust differences in health insurers' costs that arise due to variations in risk profiles.
